Abstract (en)
[origin: US2007015542A1] A sensor for obtaining vehicular traffic data is described. The sensor includes a housing having a front surface. The sensor also includes an antenna plate having an antenna ground surface and a radiating surface. The antenna plate is disposed within the housing for transmitting radiation to a vehicle through the front surface and for receiving the radiation reflected back from the vehicle through the front surface. A transceiver circuit plate is disposed within the housing for electrically driving the antenna plate. The transceiver circuit plate has a component side for supporting circuit components and a circuit ground side for grounding the circuit components. The antenna ground surface is between the radiating surface and the transceiver circuit plate. A processor unit drives and processes electrical signals from the transceiver circuit plate to obtain vehicular traffic data.
